NOAA OWP NextGeneraton Modeling Framework Hydrofabric

What is it?

Nextgen hydrofabric artifacts are distributed by NHDPlusV2 Vector Processing Units. They are built from a set of national reference datasets cite such that they are easily updated, manipulated, and quality controled to meet the needs of a wide range of modeling tasks.

How do I get it?

Nextgen artifacts are publicly available through a partnership with Lynker and the NOAA OWP by VPU. For each VPU two artifacts are available

• a geopackage that conforms to the upcoming OGC standard for hydrofabrics for modeling cite.
• a zip folder containing the files needed to run the Next Generation (Nextgen) Water Modelling Framework.

These can be programatically accessed using the respective URL patterns:
